Question

Awful connection speeds over VPN

I just got set up and going with pptpd. I can connect. I can browse, kinda. I cannot get any speed test to work except google’s when connected to the VPN which reports 4Mb/s down and 4.72Mb/s up. The upload seems about right for my connection but the download is nowhere near what my home connection should be at.

Home without vpn:

Home with vpn:

cannot get speedtest.net or speedof.me to even load, google reports above.

DO vps:

Retrieving speedtest.net configuration… Testing from DigitalOcean (138.197.223.87)… Retrieving speedtest.net server list… Selecting best server based on ping… Hosted by Sneaker Server (San Jose, CA) [11.20 km]: 13.141 ms Testing download speed… Download: 1853.16 Mbit/s Testing upload speed… Upload: 461.74 Mbit/s

Tracert reveals nothing of value to me.

Trace complete.

By all metrics the droplet should be able to saturate my connection on the download but its not even coming close. Am I being throttled in some way? Is there something wrong with using pptpd vs openvpn?

I’m not sure what you want to see when you say “how you setup your VPN”. I literally followed the DO guide to pptpd.

I realize that I’m never going to see the ~135Mbps down I get normally. However I expected better than 4Mbps. FrootVPN for example has no problem getting me over 100Mbps over the vpn connection. I would expect roughly the same from my droplet but maybe thats wishful thinking. Maybe I should have went with linode instead since they offer servers much closer.

When connecting to a VPN, you’re not going to see the exact same speeds you do when connecting to your local network. This is due to a multitude of things, though distance and security level are two of the biggest factors. The connection between where your connection comes from (i.e on Charters’ side) and the Droplet (i.e. DigotalOcean’s Data Center) also play a factor (i.e. interconnection).

The farther you are from the physical location of the VPN, the bigger the drop. Likewise, higher levels of encryption will also result in slower speeds. Depending on what your local connection is capped at, you should realistically expect ~50% of that when connecting to a VPN, though this is not a definite.

For example, I’m with Charter as well here in Tennessee and I have a 60Mbps connection. I normally see about 60-68Mbps on average, when not connected to a VPN. When I am connected, I may see 20-30Mbps and I may see a little less (i.e. 15-20Mbps).

In terms of a lack of connection, that really depends on how you setup the VPN. Before we can really look in to connection issues, we’d need to know how you setup your VPN. If you can provide that info we can take a better look at what’s going on.
